Hi @Nico_11 Alienware R2 insufficient descriptor, please click on Product Support and let Dell identify your Model and Revision number. (Do not post your private Service Tag in this public forum.)
You have a 2016 out of warranty 15 R2. I have edit the thread title adding the model. Run the LCD Built-in Self-Test as mentioned by ejn63. I would also try attaching an external monitor to the 15 R2 rear HDMI out port to see if it shows a display.
Hi @Nico_11 welcome to this user to user discussion forum. This is not Dell Support.
Alienware 15 R4 Diagnostic says 8 light code, is either 2,6 = System-board or chipset error, or 3,5 = Power-rail failure
A replacement Alienware 15 R2 motherboard is seemingly required.

The current Alienware 15 R2 BIOS v1.12.0 is dated 15 Apr 2021 and should have modern beep codes. The 20 Jul 2021 Beep Codes on a Dell Notebook PC for Inspiron, Latitude, Vostro, XPS say 8 = LCD Failure. Did not find Alienware list of Beep Codes.
Hi @mattyb3 thank you. This list is similar to (1) Understanding Beep Codes on a Dell Notebook PC, and (2) Understanding Beep Codes on a Dell Desktop Personal Computer.

Eight beeps does mean an un-identified display panel.
Can you get the screen diagnostics to run (hold the D key through powerup) or does the display remain black?

It's an 8 beep error code, most likely related to the LCD panel or display cables. These older laptops didn't use light sequence codes.

I agree with mattyb3 and Chris. It’s most likely the LCD and it probably needs replacement. I can link you a screen and what’s great is that if you don’t have the glass front panel type of screen and only the plastic bezel one replacement is very easy. https://www.amazon.com/BRIGHTFOCAL-Alienware-1920x1080-Replacement-Display/dp/B07ZNKS2V4/ref=sr_1_3?dchild=1&keywords=Alienware+15+r2+screen&qid=1627530691&s=electronics&sr=1-3
